We always put out some type of lighting around our trailer when camping. This year the rope lights we usually put around our trailer had so many sections burned out that we decided to replace them.
Walmart had some LED rope lights on sale so we bought enough strands to go around our fifth wheel.
Dumb move on my part, I picked out blue. Every time we used these lights this year we seemed to be inundated with flying insects. DUH!! Bug zappers use blue lights. Insects are attracted to blue light. Time to look for rope lights again.
